오늘날의 기업은 상품을 판매하는 것 뿐만 아니라 기업의 신용과 이미지를 위해 그 상품에 대한 사후처리(After Service) 업무에 많은 투자를 하고 있다. 이러한 양질의 사후서비스를 고객에게 공급하기 위해서는 많은 인력을 합리적으로 관리해야 하고 요청되는 고장수리 서비스 업무를 빠르게 해결하기 위해서는 업무를 인력들에게 합리적으로 배정을 하고 회사의 비용을 최소화하면서 정해진 시간에 요청된 작업을 처리하기 위해서는 인력들에게 작업을 배정하고 스케줄링하는 문제가 발생된다. 본 논문에서는 이러한 문제를 해결하기 위해 화학계기의 A/S 작업을 인력에게 합리적으로 배정하는 스케줄링 시스템에 관한 연구이다. 먼저 스케줄링 모델을 HP 사의 화학분석 및 시스템을 판매, 유지보수 해 주는 "영진과학(주)"회사의 작업 스케줄을 분석하여 필요한 도메인과 고객서비스전략과 인력관리전략에서 제약조건을 추출하였고 여기에 스케줄링 문제를 해결하기 위한 방법으로 제약만족문제(CSP) 해결기법인 도메인 여과기법을 적용하였다. 도메인 여과기법은 제약조건에 의해 변수가 갖는 도메인의 불필요한 부분을 여과하는 것으로 제약조건과 관련되어 있는 변수의 도메인이 축소되는 것이다. 또한, 스케줄링을 하는데에 있어서 비용적인 측면에서의 스케줄링방법과 고객 만족도에서의 스케줄링 방법을 비교하여 가장 이상적인 해를 찾는데 트래이드오프(Trade-off)를 이용하여 최적의 해를 구했으며 실험을 통해 인력에게 더욱 효율적으로 작업들을 배정 할 수 있었고 또한, 정해진 시간에 많은 작업을 처리 할 수 있었으며 작업을 처리하는데 있어 소요되는 비용을 감소하는 결과를 얻을 수 있었다. 검증하였다.를, 지지도(support), 신뢰도(confidence), 리프트(lift), 컨빅션(conviction)등의 관계를 통해 다양한 방법으로 모색해본다. 이 연구에서 제안하는 이러한 개념계층상의 흥미로운 부분의 탐색은, 전자 상거래에서의 CRM(Customer Relationship Management)나 틈새시장(niche market) 마케팅 등에 적용가능하리라 여겨진다.선의 효과가 나타났다. 표본기업들을 훈련과 시험용으로 구분하여 분석한 결과는 전체적으로 재무/비재무적 지표를 고려한 인공신경망기법의 예측적중률이 높은 것으로 나타났다. 즉, 로지스틱회귀 분석의 재무적 지표모형은 훈련, 시험용이 84.45%, 85.10%인 반면, 재무/비재무적 지표모형은 84.45%, 85.08%로서 거의 동일한 예측적중률을 가졌으나 인공신경망기법 분석에서는 재무적 지표모형이 92.23%, 85.10%인 반면, 재무/비재무적 지표모형에서는 91.12%, 88.06%로서 향상된 예측적중률을 나타내었다.ting LMS according to increasing the step-size parameter $\mu$ in the experimentally computed. learning curve. Also we find that convergence speed of proposed algorithm is increased by (B+1) time proportional to B which B is the number of recycled data buffer without complexity

Fusarin C, which had been produced in cereals by Fusarium moniliforme, was known as a mutagen. In this study, natural occurrences of fusarin C in 12 kinds of cereals grown in Korea, fusarin C production by F. moniliforme in cereal cultures, and the relation between fusarin C production and water activity were investigated. The results were obtained as follows; 1. Fusarin C was detected large amounts in rice, glutinous millet, sorghum millet, and corn obtained from Seoul markets randomly. But in cereals selected from Pyungtaik market, fusarin C was detected in barley and job's tears only. The amounts were much lower than those from Seoul markets. It was thought that keeping conditions of cereals during retailing period were very important factors to natural occurrences of fusarin C. 2. The amounts of fusarin C production were determined much more in rice and barley cultures with F. moniliforme. In this study, the facts are made clear that rice and barley had been more proper than corn to produce fusarin C by F. monilifome. 3. Water activity had more effect on fusarin C production in corn cultures than rice cultures. In corn cultures, water activity was higher, and the amounts of fusarin C production was larger. In case of high activity (Aw 0.85), the amounts of fusarin C was shown the largest in 1 week after then was decreased rapidly.

This paper compares the realities of the salary Peak Policy's status and management processes in Korea and Japan, with the aim of determining the development direction for Korea's salary Peak Policy's. Unlike Japan, which successfully achieved close cooperation between government, firms and workers in implementing the Retirement Age Extension Type salary Peak Policy, Korea experienced many problems due to lack of preparation. In order to rationally develop the salary Peak Policy, the government, firms, and workers must cooperate to increase the policy's efficiency via the following steps. First, gradually increase the proportion of retirement age extension. Second, career development that takes into account the various employment types, flexible working hours and aged workers. Third, development of training programs for senior citizen workers, as well as increasing support for changing of jobs and startups. Fourth, expansion of re-employment after retirement age and ways to make use of the skilled labor. Fifth, increasing work efficiency through bonuses and work evaluation that is specialized for aged workers. This paper argues that such measures are necessary for the co-existence of firms and workers, as well as for improving employment stability and labor market flexibility.

Thus study examined the possible the link between social enterprises and lifelong education for the underprivileged. To this end, this study searched for the definition and position of social enterprises emerging from the welfare system under the influence of neoliberalism and overcoming the problems in terms of creating social jobs and providing welfare services. In addition, the lifelong education for the underprivileged was examined according to the subjects, such as the disabled, migrant women, young and adult low-income group, and senior citizens. The plan was as follows. First, the expansion of the proportion of community-affiliated social enterprises was analyzed. Second, it provides a differentiated support and protection market for social enterprise. Third, the development and dissemination of social entrepreneur training programs was examined. The results showed that the entire society should have a sense of responsibility for the support of the underprivileged. This provides implications for the linkage of lifelong education and social enterprise in the expansion possibility to improve the quality of life and expand lifelong education for the underprivileged.

It has been two years since the national certificate of Arts & Culture Education Instructor(ACEI) was implemented the 2012 amendment to the Arts & Culture Education Act. Separate from the initial policy goals, students who attend the program to achieve ACEI certificate share various expectations, motivations and intents. The purpose of the research is to understand the collective identity of future ACEIs to evaluate the initial policy implementation during the period when the collective professional identity has not been fully formed yet. This research studies the data that were collected from 172 students who were attending one of the official ACEI institutes in Seoul area. As one of qualitative research methods, Questionnaire Method was employed to conduct this phenomenological study. James E Marcia's theory provides the theoretical framework for the data analysis of this study. The research results indicate that many students'identity status are between Identity Diffusion and Moratorium, which raises concerns for both arts and cultural fields as well as the policy success. Therefore, this research will relate these findings to the larger arts and culture infrastructure in order to better prepare them as arts and cultural professionals and also to stress the importance of the job market development and social environment that can accept them.

This paper explores the characteristics of innovation activities in high growth firms that contribute to national and regional economic growth and job creation. The analysis is based on the 2016 KIS data to analyze the difference in innovation activities between high growth firms and general firms. The main results are as follows: First, high growth firms have a higher proportion of R&D personnel than general firms. Second, high growth firms are actively introducing product innovation, process innovation, and organizational innovation as compared to general firms. In the innovation activities related to product innovation and process innovation, there is no statistically significant difference between high growth companies and general companies except for external R&D. Third, High growth firms are more likely to cooperate with other technology partners than general firms. But, there is no statistically significant difference between high growth firms and general firms in the external knowledge search and the diversity of cooperating partners. Fourth, in terms of protecting innovation, high growth firms are more likely to use all kinds of innovation protection method, such as 'utilizing intellectual property rights', 'maintaining confidentiality', 'adopting complex design methods', 'market preemption ahead of competitors', and the most important means is the intellectual property rights. Fifth, government innovation policies that high growth firms chose as important are 'innovation subsidies and loans', 'acquirement, utilization and protection of intellectual property rights' and 'human resource support'.

With the aging of the population and the slowdown of the job market, elderly workers make up a large portion of the construction workforce. Also, due to the nature of the construction industry, where outdoor work is frequent, the weather has a more sensitive impact on elderly workers than on younger ones. The study aims to analyze the degree of weather risks exposed to elderly workers in the construction industry using the measure of work loss days. To that end, construction accidents that affected 28,514 elderly workers in seven cities from 2012 to 2016 (a total of 12,789 days) were analyzed to calculate work loss days per different weather factors. The results show that the elderly workers were seriously affected when the temperature was between $-12^{\circ}C$ and $-10^{\circ}C$, humidity between 55% and 60%, precipitation between 128mm and 181mm, and wind speed between 5.5m/s and 6.5m/s, with the highest work loss days. The combined effects between the weather factors were also analyzed to identify the conditiosn that leaded to high work loss days of elderly workers. This study contributes to effective safety management and pleasant working environment between weather factors and shedding light on the relationship between weather factors and work loss days of elderly workers.

As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitment, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with task processing and organizational performance filed is 'task processing capability group', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' task processing capability group on their career outcome expectation and career preparation behavior. In this study, we set up a process model to comprehend the effect of college students' task processing capability group on career outcome expectation and career preparation behavior based on social cognitive career theory. Empirical analysis showed that task processing capability group(problem-solving capability, information capability, resource management capability, organizational capability) positively influenced college students' career outcome expectation and career preparation behavior for employment. However, the impact of technical capability on career outcome expectation and career preparation behavior was not explained. In order to strengthen the task processing capability group of college students, not only university-level efforts, but also college and faculty's efforts should be accompanied. Other academic and practical implications are discussed.

This study pays attention to the restricted use and the possibility of standard position of contingent workers in Brazil. The labor market of Brazil has been developed by formal and informal labor sector, and informal sector includes various precarious workers as well as contingent workers. According to Brazilian Statistics Department, not contingent workers but informal labor focused in this paper have been slowly decreased since year 2000. In this context, this study investigated on the reasons of decreasing contingent employment in Brazil. The results demonstrate that decreased informal employment and instead increased standard workers could not be interpreted by recent the Braizil's economic boom. Along with literature review, the author conducted the case study regarding employment of contingent workers at six large foreign companies in Sao Paulo. The results of this show that the use of contingent employment was prohibited in regular daily works by the labor law and thus firms employed contingent workers in only temporary positions. Further, firms often promise standard positions for contingent workers when temporary employment contract was terminated since there is little or no exist of the differences of wage between standard and contingent worker in terms of 'same work same wage' and 'minimum wage'. In here, labor unions play a key role in employment change from contingent position to standard job. Consequently, decreasing of contingent workers and stepping stone to regular jobs seems to be triggered by both legal regulation on contingent employment and strong unions. This institutional perspective may extend the theoretical view on the use of contingent workers, and the author discuss that Brazil's case could provide practical implications to Korean labor policy.

Part-time jobs in Sweden are highly feminized yet are in fair conditions in terms of job security, earnings, and collective representation. Three points are considered to be important to understand why part-time work in Sweden carries such positive characteristics. First, the part-time work in Sweden is widely spread not as a result of employers' need for labor flexibilization but as means to enhance the work-life balance, a value pursued within a broader social policy package to change the breadwinner model. Second, discrimination against part-time workers is restrained in Sweden because the boundary between part-time and full-time is not conspicuous. Most of part-time jobs are occupied by regular workers who exert the right to part-time work, hence may go back to the full-time status any time. Third, the regulation on overtime work of part-time workers as well as full-time workers is strong. It is largely agreed among researchers that part-time work contributed greatly to an increase of female employment rate in Sweden. Since the 1970s, the increased availability of part-time jobs induced married women who used to be economically inactive to the labor market and maintained them to be economically active throughout the child rearing period. From the gender perspective, one may still raise issues regarding part-time work in Sweden such as persistent feminization and strong occupational sex segregation. However, the observed trend shows that the part-time work in Sweden has functioned more as a stepping stone to the full-time work for women than as a women's trap.
